| 摘 要： | 在已有试验研究资料基础上,综合分析了十字形、L形和T形型钢混凝土异形柱在轴心荷载作用下受力过程,试验表明其破坏过程大致相同,都经历了3个阶段,即弹性阶段、带裂缝工作阶段和破坏阶段。L形在轴心荷载作用下发生了一定程度的双向弯曲,与普通钢筋混凝土异形柱相比,型钢能有效抵抗双向弯曲。通过分析破坏过程及试验数据资料,最后给出了适用于T、L及十字形异形柱的轴心受压承载力计算公式,以供设计参考。

| Abstract: | Based on the data of experimental research,the failure processes of shaped-steel reinforced concrete special-shaped columns are analyzed.It is indicated that the failure processes are similar and can be described as three stages,i.e.the elastic stage,elastic-plasitc stage and failure stage.The L-shaped column undergoes the biaxial bending failure under axial loading,and compared with the ordinary columns,the shaped-steel columns can resist the biaxial bending failure effectively.Then the calculation formula... |
